B'pads...Like your idea, but scrog might be a little tedious for a new grower.

On another note...i must disagree with this statement;
Once you have added the total volume of the res about 2-3 times, do a res change and start it fresh.

You wouldn't have any nutes/ppm left...you shouldn't ever top-off more than 100% of volume before nute changeout.

anyway welcome to cdot...see ya around.

latewood Reviewed by latewood on . Maintaining a DWC system. Im interested in building my own DWC system out of a sterilite tub. I've been reading lots of members post about the DWC system and know pretty much all the basics of it. I do have a few questions though that keep coming to my mind that i can't seem to find answers for. If these questions were asked before i apologize. 1: On the dwc system, how do you "top off" or even flush and refill the tub? Im sure just taking the lid off or pulling one of the netpots out to refill is not the best way. Rating: 5
